BSP invalid due to wrong characters in URL

Question

Hi all,
Anybody have had next problem.
Next URL is executed :
https://secure.securex.be/crm1/sap/bc/bsp/sap/sem_bsc/analysis.htm
Via the reverse proxies ichain and Teros, the service is changed to
/sap%28bD1ubCZjPTYwMA%3D%3D%29/bc/bsp/sap/sem_bsc/analysis.htm instead of /sap(bD1ubCZjPTYwMA==)/bc/bsp/sap/sem_bsc/analysis.htm.
If we go directly to the backend, the last service is recognized and executed well.
Through the ichain and Teros, instead of" (, =, )", "%28, %3D, %29" is genareted what is not recognized by the ICM of SAP.
Other webservers like Lotus Notes and  BEA Weblogic recognize such characters without any problem.
Any idea what parameters needs to be set?
Massage from SAP :
BSP Exception: the Application Name bc in URL /sap%28bD1ubCZjPTYwMA%3D%3D%29/bc/bsp/sap/sem_bsc/analysis.htm is invalid.
Anybod can help me.
Kind Regards
Paul

I had some issue with reverse proxy and I use IIS Proxy to make it. I solved issue with entries like below .
We have to put entry for proxy server in HTTPURLLOC table. More details available in https://www.sdn.sap.com/irj/sdn/wiki?path=/display/bsp/using+proxies&
Again when we call BSP the URL is changing with some extra string to replace /bsp/ to /bsp(xxxxxxxxxxxxx)/.
And for EP 7.0, other than the two entries required for EP 6.0 ( they are /irj/ and /logon/ ), we have to put one more entry for WebDynpro.
So finally the entries in IISProxy.xml file looks like below. ( In the below example 'sapep' is Portal and 'sapecc' is ECC 5.0 server.)
<ISAPI-config version="1.6">
<filter name="IisProxy filter" />
<extension name="IisProxy extension" />
<mapping name="PORTAL">
<source>
<protocol>http</protocol>
<prefix>/irj</prefix>
<new-prefix>/irj/</new-prefix>
